Let us introduce an algorithm with a function CanEmpty() which takes a string P as a parameter and return TRUE if it is possible to make P empty, otherwise return FALSE.

String P consists of only 0 and 1. The pseudo-code implementation of CanEmpty() function is as follows.

bool CanEmpty(String P)

{

    while(P has at least one substring 100)

    {

        Chose any one substring 100 in P and delete it.

    }

    if(P is empty) return TRUE;

    else return FALSE;

}

Now you are given a string S consisting of 0 and 1, you have to find the length of longest substring of S that can be made empty applying CanEmpty() algorithm.

As for example, let S=1011100000100

S has only two sub-strings (bold) which can be made empty applying CanEmpty() algorithm.

The first substring will have the delete- sequence in CanEmpty() function :

110000->100->empty

The second substring will have the delete-sequence in CanEmpty() function:

100->empty

The length of first substring is 6 and second is 3. So, the required answer is 6.

Input

Input starts with an integer T (≤ 100), denoting the number of test cases.

Each case contains a string S. The size of string is at most 200000.

Output

For each test case, print the case number and required answer.
